[0048] Example implementation environment

[0049] Please refer to FIG. 1 , FIG. 1 The application relates to an implementation environment.

[0050] As FIG. 1 shown, the implementation environment of the embodiment of the application relates to a server and a vehicle, wherein the range extender electric vehicle comprises a vehicle controller, a range extender, a range extender controller, a generator, a generator controller, an engine and an engine controller. The range extender controller can obtain a power generation parameter, a power generation time and an idle operation time, and the vehicle controller can obtain a driving distance of the vehicle. The vehicle controller can send the above parameters to the server, so that the server processes the power generation parameter and the operation parameter, judges whether the vehicle needs to be maintained, and sends a maintenance instruction to the vehicle when the vehicle needs to be maintained.

[0051] Server 1 can be a standalone physical server, a server cluster or distributed system consisting of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. The server can also become a node in the blockchain.

[0052] Server 1 may be one or more servers. When there are multiple servers 1, at least two servers are used to provide different services, and / or at least two servers are used to provide the same service, such as providing the same service in a load balancing manner, which is not limited in this embodiment of the present invention.

[0053] In addition, it also includes terminal equipment, which can be directly or indirectly connected to the server through wired or wireless communication, or the terminal equipment can be used to replace the server. FIG. 1 The server in the application is not limited in this application. The application does not limit the number of servers or terminal devices. The solution provided by this application can be completed by the terminal device independently, by the server independently, or by the terminal device and the server in combination, and this application does not limit this.

[0054] It should be understood that FIG. 1 This is only an illustrative description and does not specifically limit the application scenarios of the embodiments of this application. For example, FIG. 1 One vehicle and one server are shown as an example, but other numbers of vehicles and servers may actually be included, and this application does not impose any limitation on this.

[0055] Example method

[0056] FIG. 2 This is a flow chart of the range extender maintenance method provided in the embodiment of this application. FIG. 2 In an exemplary embodiment, a range extender maintenance method is provided, which may include:

[0057] S220: Obtain power generation parameters and operating parameters of the range extender.

[0058] The range extender may include components such as the engine, spark plugs, and belts.

[0059] The range extender can extend the cruising range by starting when the battery power is below a preset threshold. The range extender will automatically start when the battery power drops to a preset low power threshold. This threshold is usually set according to the design and use of the vehicle, and the common threshold range is 20% to 30%. In addition, some vehicles (e.g. special vehicles) may dynamically adjust the starting threshold according to driving mode, speed, road conditions, etc. For example, when driving on the highway, a higher starting threshold may be set to ensure sufficient cruising range.

[0060] The range extender power refers to the power provided by the combination of the engine and the generator, which is used to charge the battery of the electric vehicle or directly power the electric motor. According to the actual power demand of the vehicle, the power of the range extender engine is dynamically adjusted to ensure that the power provided by the generator matches the demand of the electric motor. The power generation parameters include the power generation power and the power generation time corresponding to the power generation power.

[0061] The idle time in the embodiment of the present application refers to the time when the range extender is in the starting state but does not generate electricity. In order to optimize fuel economy, reduce emissions, maintain the working temperature of the thermal management system, and improve the comfort of driving and riding, the range extender enters the idle state but does not generate electricity to ensure efficient operation of the vehicle. The operating parameters include the power generation operating time, the idle operating time and the driving distance.

[0062] S240: Determine the power generation amount of the range extender according to the power generation power and the power generation time corresponding to the power generation power.

[0063] The power generation amount of the range extender is the product of the power generation power and the power generation time corresponding to the power generation power.

[0064] S260: Determine the operating time of the range extender according to the power generation operating time and the idle operating time.

[0065] The operating time of the range extender is the sum of the power generation operating time and the idle operating time of the range extender.

[0066] It should be noted that S240 and S260 do not have an execution order.

[0067] S280: When the first preset condition or the second preset condition is met, send a maintenance instruction to maintain the range extender; the first preset condition is that the power generation amount of the range extender exceeds the power generation threshold, and the driving distance exceeds the distance threshold; the second preset condition is that the operating time of the range extender exceeds the operating time threshold.

[0068] In this embodiment, the maintenance distance limit of the fuel vehicle is used as the equivalent power generation amount of the range extender vehicle, and the equivalent power generation amount is used as the power generation threshold. In actual application, the equivalent power generation amount can be determined by the first formula, and the first formula is:

[0069] Q=S / 100*K

[0070] Wherein, Q is the power generation threshold, unit: kilowatt; S represents the mileage of a fuel vehicle within a maintenance period, which can be determined according to historical data. Unit: kilometers; K is the power consumption per 100 kilometers, unit: kilowatt hours per 100 kilometers.

[0071] The running time threshold can be determined according to the second formula, and the second formula is:

[0072] T=Q / P max

[0073] Wherein, T is the running time threshold, unit: hour; Q is the power generation threshold, P max The maximum power generation of the range extender in the parking state, unit: kilowatt.

[0074] The first preset condition in the embodiment of the application is that the range-extended power generation exceeds the power generation threshold, and the driving mileage exceeds the mileage threshold, which can eliminate the situation of maintenance surplus, and can also ensure that the engine does not exist excessive maintenance, frequent maintenance and other phenomena, avoiding high maintenance cost and customer complaints. The second preset condition is that the running time of the range extender exceeds the running time threshold, which can avoid the situation that the range extender has small power generation but the engine cannot be maintained for a long time.

[0075] The embodiment of the application considers the actual load of the range extender by calculating the range extender power generation and driving mileage, which can truly reflect the maintenance demand of the range extender.

[0076] In one embodiment, determining the range extender power generation according to the power generation and the power generation time corresponding to the power generation can include:

[0077] Obtaining each power generation time period and the power generation in the power generation time period, the power generation in the same power generation time period is the same;

[0078] For each power generation time period, the product of the power generation time period and the power generation in the power generation time period is calculated to obtain the segmented power generation of the range extender corresponding to the power generation time period;

[0079] The segmented power generation of each power generation time period is accumulated to obtain the range extender power generation.

[0080] Since the power generation of the range extender is different in actual application scenarios, in order to accurately calculate the range-extended power generation, the segmented power generation is calculated in actual application, and the range extender power generation is determined by accumulating the segmented power generation, which improves the accuracy of the range extender power generation calculation.

[0081] In one embodiment, determining the running time of the range extender according to the power generation running time and the idle running time can include:

[0082] determine the equivalent running time according to the idling running time;

[0083] calculate the sum of the power generation running time and the equivalent running time to obtain the running time of the range extender.

[0084] The equivalent running time can be the total of the idling running time converted to full load running time during the actual running process of the range extender. The equivalent running time takes into account the efficiency difference of the range extender under different working conditions, and provides a more accurate running time evaluation.

[0085] In actual application, the equivalent running time can be calculated by a third formula, which is:

[0086]

[0087] wherein: T i is the idling running time in the i-th time period, in seconds; P i is the actual output power in the i-th time period, in kilowatts; P max is the maximum output power of the range extender, in kilowatts.

[0088] In actual application, the equivalent running time can be determined by presetting equivalent parameters. The preset equivalent parameters can be a constant, for example, the preset parameter can be 0.1.

[0089] The running time of the range extender can be determined by a fourth formula, which is:

[0090] T0 = T1 + 0.1 * T2

[0091] wherein, T0 is the running time of the range extender, T1 is the power generation running time, and T2 is the idling running time.

[0092] In one embodiment, the process of obtaining the idling running time can include:

[0093] determining the start time of the idling running time in response to the idling instruction issued by the range extender controller; determining the end time of the idling running time in response to the exit idling instruction issued by the range extender controller;

[0094] determining the idling running time of the range extender based on the start time of the idling running time and the end time of the idling running time.

[0095] determining the power generation running time of the range extender based on the start time of the power generation running time and the end time of the power generation running time.

[0096] After the range extender controller sends the idling instruction, the engine and the generator of the range extender will execute corresponding operations according to the instruction, the engine adjusts the rotating speed, and the generator no longer outputs current, at this time, the start time of the idling running time is determined; after the range extender sends the exit idling instruction, the end time of the idling running time is determined.

[0097] The start time of the idling running time and the end time of the idling running time are determined through the idling instruction of the range extender controller, which can improve the more accurate determination of the idling running time of the range extension, and provide accurate data support for the maintenance of the range extender.

[0098] In an embodiment, the power generation running time acquisition process comprises:

[0099] In response to the power generation instruction sent by the range extender controller, the start time of the power generation running time is determined;

[0100] In response to the exit power generation instruction sent by the range extender controller, the end time of the power generation running time is determined;

[0101] Based on the start time of the power generation running time and the end time of the power generation running time, the power generation running time of the range extender is determined.

[0102] After the range extender controller sends the power generation instruction, the engine and the generator of the range extender will execute corresponding operations according to the instruction, the generator starts to work to charge the battery or power the motor, at this time, the start time of the power generation running time is determined; after the range extender sends the exit power generation instruction, the engine gradually reduces the rotating speed and finally stops running, and the end time of the power generation running time is determined.

[0103] The start time of the power generation running time and the end time of the power generation running time are determined through the power generation instruction of the range extender controller, which can improve the more accurate determination of the power generation running time of the range extension, and provide accurate data support for the maintenance of the range extender.

[0104] In an embodiment, after sending the maintenance instruction to maintain the range extender, the method can further comprise:

[0105] The power generation amount of the range extender is accumulated to the total power generation amount of the range extender;

[0106] The driving mileage of the range extender is accumulated to the total driving mileage of the range extender;

[0107] The running time of the range extender is accumulated to the total running time of the range extender;

[0108] The power generation amount of the range extender, the driving mileage of the range extender and the running time of the range extender are zeroed.

[0109] The total power generation, total driving distance and total running time of the range extender are important indicators for evaluating the performance and efficiency of the range extender vehicle. The working state of the range extender and the endurance of the vehicle can be reflected by the statistics of the total power generation, total driving distance and total running time. Through comprehensive analysis of these indicators, the power generation strategy can be optimized, the energy efficiency can be improved, the emissions can be reduced, and the user's driving experience can be improved.
